Light Sensitive: manananggal are sensitive
to sunlight and effects which mirror it (such as the daylight spell) and are at
disadvantage on all actions while exposed to direct sunlight.

Vulnerable to Light Blades: light
finesse blades deal double damage to manananggal which are magically
susceptible to the fine light metal of the weapon for supernatural reasons.

Special Vulnerabilities: manananggal
dislike garlic and salt, and will avoid it if possible though no specific harm
comes to them. They are susceptible to the strike of a stingray barb, which if
fashioned in to a weapon (such as a whip) can deal normal damage but the
manananggal then suffers disadvantage on its next attack roll until the end of
its next turn.

Separating Flying Undead Torso: by day,
a manananggal looks like a normal living human or elven woman, and does not
detect as (nor act) undead. At sunset the manananggal’s torso rips away from
her legs/lower torso and takes flight, transforming into a terrifying
half-bodied vampiric entity. In this form the undead is aware of attacks
against her lower torso, which shares the same hit points; destroying the lower
torso requires applying garlic and salt to the separation point, and doing so will
prevent the upper body from grafting at dawn, causing it to turn to dust--so
the manananggal takes special care to separate somewhere safe. Physical damage
to the lower torso can cause the manananggal to dissipate into a mist which
then seeps in to the earth to revive fully
formed at dusk the following evening; only by tainting the lower torso
with garlic and salt, preventing reunification, will the creature perish.

Spells: Manananggal are often warlocks
and sorcerers, and all manananggal have access to the following spells with a
spell attack modifier of +6 and a spell save DC of 14:

At Will: chill touch, dancing lights

3/day: darkness, sleep, ray of enfeeblement,
fear

The manananggal
is an undead Phillipino vampiric beast whose name derives from an original
meaning of “separate” in reference to its ability to rend its own body in two
pieces to take flight as it transforms at dusk. The manananggal. It intensely
dislikes garlic and salt, and is damaged by light weapons, as well as the barb
of the stingray.

The lore of
the manananggal is that it exudes black proboscis-like tongue to drink the
blood of sleeping victims. It favors pregnant women, drinking the blood of
their unborn children’s hearts.

By day the
manananggal goes about its business, oblivious to its own existence as an
undead being, though whether this is a magical effect or a ruse is unknown.
They can thrive in remote villages for years sometimes, drinking only enough
blood to weaken many of their kin over time without killing them, though
villages plagued by such undead predators are noted for a high rate of
stillborn children, unusual sickness, and
a sense of “wrongness” in the region.

When a
manananggal wears out its welcome or has dwelt in one region for too many years
it will quietly leave and seek out a new territory on which to prey.

The important thing is that in a million years, when the brain-worms of Arcturus IX have annihilated us throughout the galaxy, there will be no surviving recordings of blogs to be found by the cephalopods that evolve to replace us. In this way will their civilization advance and prosper.
